:the top of said frame, said motor being adapted to communicate itspower to said pulley 8, the belt 7 and the pulley 6, and consequently tothe shaft 4 whereby the planing member 3 receives its rotary motion.Said member 3 consists of a head 11 and a series of blades or cutters12, which latter occupy positions in recesses 13 in the peripheral rtionof said head and are retained therein by the blocks-.14 and the bolts15, said blocks being of pyramidal or'wedge shape form to fit saidrecesses and bear respectively against the opposite side walls of saidrecesses and the sides of said blades, whereby the latter are adapted tobe adjusted on the'head and retained firmly in set position thereon. Thebase of the chamher 2 is open, forming the throat 16 through which asthe planing member revolves the cutting edges of the blades rotrude tosufficient extent to engage t e floor to be planed.

The frame of the device is supported on the shoes 17, which aresubstantially triangular in vertical section and have their innerportions separated from each other at the throat 16, the under faces ofsaid shoes being plane surfaces so as to run flat on the floor, theirupper walls 18 being inclined and slidingly engaging inclined surfaces19 on the adjacent portions of the frame 1, said surfaces havingdepending flanges 20 on which are swivelled the bolts 21 whose threadsengage threaded ears 22 on the upper walls 18 0f the shoes whereby, byoperating said bolts, the shoes may be approached or se arated to raiseor lower the frame and wlth it the cutter, thereb varying the depth ofcut of the latter an at the same time, increasing or decreasing thewidth of the throat 16.

On each side of the shoes are the depth gages 23 which consist ofhorizontal mombers 24 one on each side of the shoes and having risingtherefrom the arms or limbs lowered so as to set their-under sides tothe required distance from the floor or boards to be planed. Then theshoes 17 are adjusted in accordance with the depth gages whereby theblades will plane the floor, to the required depth. Furthermore, when alength of a floor has been planed, the depth gage moves alon theshoulder formed on the floor by the p aned portion of the latter, and soassists in guiding the device true in its motions on the floor duringthe planing operation, see Figure 2.

, Attentionis drawn to the fact that the shoe that is foremost is raisedto a small extent so that its under face .will ride on the unplanedfloor or board, and that the shoe that is in the rear has its under faceslightly lowered so as to ride on the planed floor or board, this beingillustrated by the differences in the base lines in Figure 2.

In order to propel the device I provide the handles 28, whose lowerportions are bolted to one or the other of the plates 19 of the frame asshown in Fig. 3 and fit between the lugs 29 onv said plate, see Fig. 2,which assist in preventing lateral shifting of the handle on said plate.

The handle may be placed on either end of the frame, as indicated inFigure 3, accord-- ing to the direction in which the machine is totravel. The upper portion of the shoes and undersides of the plates 19are formed with grooves and tongues respectively as shown at 30, Figure9, to assist in preventing the shoes from shifting laterally bolts 31being also passed through said portions and 1 plates to provide firmconnections of the shoes in position.

Connected with the shoes are the arms 32 on whose outer portions aremounted the horizontally extending rollers 33 which are adapted to bearagainst a side wall, surbase or wainscoting of an apartment in which theplaning is being performed, thus assisting to guide the machine true inits movements in either direction.

The shaft 4 is shown extended in full lines, Figure 7 and in dottedlines Figure 6, so as to have mounted thereon the planing me ..*.ber 34for side work when so desired.

In the frame above-the planing member 3 is the chamber 35 whichcontainsthe fan or blower 36 whose shaft 37 is journalled in the wall ofsaid chamber and carries the pulley 38 with which the belt 7 is adaptedto contact tangentially to rotate said blower.

The chamber 35 communicates with the chamber 2 of the planing member 3and is provided with an upwardly extending chute.

39 as an outlet .for shavings or cuttings occasioned in the planing of.the floor which are drawn therefrom by the operation of the blower.

In order to gather the shavings or cuttings, there is connected with theouter terminal of the chute 39 the sack or bag 40 which is incommunication with said chute and attached thereto by-the catches 41which are on the mouth of the bag and adapted to engage a shoulder 42 onthe adjacent end of the chute, permitting also the ready removal of thebag from the chute and consequently from the device.

Secured to a proper portion of the frame 1, and rising therefrom is thestandard 43 with "which is removably connected as at 44 the 46 of suchdiameter that it is above the floor so that the machine may be tiltedand run over afioor without the planlng member contacting therewith.

47 designates a trimmer see Fig. 8 which consists of a circular bladewlth a toothed periphery, the hub portion of said blade being adapted tobe mounted on the drivlng shaft 4 so that when required the periphery ofthe blade maybe presented to the end portions of the flooring boards andso cut off said portions and so trim the boards smooth and of the samelength.

The driving shaft 4 is partly conical and partly cylindrical, theconical portion passing through a conical bore of the hub of the planerhead 11, and the cylindrical part passing through the bushing 48 of thepulley 6, the outer terminal of said cylindrical part being threaded forthe engagement of the nut 49, whereby when said nut is tightened, saidshaft is held firmly and properly in position.

A portion of the said bushing is inclosed in a sleeve 50 and the latteris mclosed in an exterior stationary sleeve 51 on the frame of thedevice. the lubricator 52 which serves to direct oil to the bushing 48for evident purposes. 1

The portion of the frame opposite to the nut 49 that forms the bearingfor the adj a-. cent end of the shaft 4 carries the lubricator 53 whichserves to direct oil to said end.

' -When the nut 49 is unscrewed the shaft 4 may be withdrawn from itsposition 'in the To said sle'eve51 is attached hub of the planing memberwithout disturbbe discharged.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is Y 1. A frame consisting of a housing for arotary cutter and a mounting for a motor for said cutter, a wallextending outwardly from said housing and inclined upwardly andbackwardly; a shoe closing more or less the lower end of said housingand having a rear portion with an inclined upper face slidably engagingthe lower face of said wall, and a screw for so slidably adjusting saidshoe to both vertically adjust said cutter and also make wider ornarrower the opening in the housing through which the cutter projects.

2. A frame consisting of a housing for a rotary cutter andamounting foramotor for said cutter, a wall extending outwardly from said housing andinclined upwardly and backwardly, a shoe closing more or less the lowerend of said housing and having a rear portion with an inclined upperface slidably engaging the lower face of said wall, and a screw for soslidably adjusting said shoe to both vertically adjust said cutter andalso make wider or narrower the opening in the housing through which thecutter projects, a handle secured to the face of the wall projectingfrom the housing, and a roller carried by a leg projecting down fromsaid handle.

3.
